CYCLE-LOCK.

Specification of Letters Patent.

Patented Sept. 12 1916.

Application filed November 30, 1914. Serial No. 874,650.

To all whom it may concern:

Be it known that I, HOWARD L. PIPPEN, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles, State ofCalifornia, have invented new and useful Improvements in Cycle-Locks, ofwhich the following is a specification.

- This invention relates to a cycle lock.

It is the object of this invention to provide a cycle lock which isadapted to be permanently attached to the cycle frame, and which is soconstructed and arranged that it can not be removed from the cycle framewhen in its locked position without severing the hasp thereby preventingthe lock being rendered ineffectual by malicious removal of the lock orhasp from the cycle frame.

Another object is to provide a pivotal mounting for the hasp or shacklewhich will permit of its being attached to cycle frame forks ofdifferent dimensions and thereby adapting the device for universal use,and whereby when the hasp is pivotally attached to one member of thecycle frame fork and extended astride a wheel spoke and the other memberof the cycle fork it will register with hasp receiving sockets in a lockrigidly mounted on the cycle frame.

Another object is to provide means for holding the pivoted hasp againstmovement when in its disengaged position.

A further object is to provide a single key controlled mechanism adaptedto engage both terminals of a U-shaped hasp.

The invention is illustrated in the accompanying drawing, in which:

Figure 1 is a view in elevation of a portion of the forks of a cycleframe illustrating the invention as applied and showing the manner ofengaging the wheel spokes to lock the cycle against use; the position ofthe hasp when not in use being indicated in dotted lines. Fig. 2 is aview in elevation of a hasp as disposed in its inoperative position.Fig. 3 is a horizontal section and plan view on the line 33 of Fig. 1.Fig. 4 is a detail in perspective of the rear portion of a bicycleillustrating the invention as applied. Fig. 5 is an enlarged detailhorizontal section of the lock as seen on the line 55 of Fig. 1 in thedirection indicated by the arrows illustrating the manner of locking theterminals of the hasp.

More specifically, 7 and 8 indicate the upwardly extending members of abicycle fork 9 on which the cycle wheel 10 is revolubly mounted; themembers 7 and 8 extending on the opposite sides of the wheel 10 in theusual manner as illustrated in Fig. 4:.

In carrying out the present invention a lock 11 of any suitable type isrigidly mounted on the fork member 7; the lock 11 being here shown ascomprising a tumbler lock of the Yale type having a casing 12 which issecured in place on the member 7 by means of a strap 13 which extendsaround the inner face of the member 7 and is secured to the lock case 12by means of screws 14: in such manner as to dispose the lock case 12 onthe outer face of the member 7 in rigid engagement therewith.

The lock case 12 is fitted with a pair of spaced openings 15 and 16 onits upper end which are adapted to receive the downturned terminations17 and 18 of a U-shaped hasp or shackle 19 which is adapted to extend onthe opposite sides of the fork members 7 and 8 astride of one or more ofthe wheel spokes 20. The hasp 19 is designed to be permanently attachedto the member 8 in pivotal connection therewith; this connectioncomprising a pair of pivotally connected links 21 and 22 which areinterposed between the connecting portion 23 of the hasp 19 and a clamp2 1 secured to the member 8. The link 21 is pivotally connected to thehasp portion 23 and the link 22 is pivotally connected to a pair ofspaced ears 25 on the clamp 21 by means of a pivot pin 26.

The clamp 24: consists of a pair of plates arranged on opposite sides ofthe member 8 which are connected together by means of screws 27 andmounted on the outermost plate of the clamp 24 is a pair of spacedspring clips 28 which are adapted to engage the side portions of thehasp when the latter are disposed vertically parallel with the member 8as illustrated in dotted lines in Fig. 1 and full lines in Fig. 2.

The links 21 and 22 form a pivotal connection which will permit the hasp19 being raised and lowered and advanced and re tracted on its pivotalconnection with the fork member 8 so that the downturned terminations 17and 18 may be readily directed into the openings 15 and 16 in the lockcase 12.

Mounted in the lock case 12 is a pair of laterally movable keepers 29and 30 which are spaced apart and have a spring 31 interposedtherebetween to normally maintain the keepers in their outermostpositions with their outer edges disposed approximately half way acrossthe openings 15 and 16 in the upper end of the lock case. The upper faceof the keepers 29 and 30 are rounded at their outer edges 32 to forminclined faces adapted to be engaged by the ends of the hasp 19 when thelatter are introduced into the openings 15 and 16 and retracted inopposition to the spring 31.

The downturned terminations 17 and 18 of the hasp 19 are formed withnotches 33 adapted to receive the keepers 29 and 30 which spring intoengagement with the notches 33 when the terminations 17 and 18 have beenintroduced. sufficiently far into the lock case.

The keepers 29 and 30 are designed to be retracted in opposition to thespring 31 by operation of the cylinder of the lock 11; the operation ofthe keepers 29 and 30 being here shown as effected by means of links 35and 36 connecting the opposite sides of the center of the lock cylinder37 with longitudinally extending slots 38 in the keepers 29 and 30; apartial rotation of the lock cylinder 37 operating to retract thekeepers 29 and 30.

The links 35 and 36 are connected to the keepers 29 and 30 by means ofpins 39 which engage the inner ends of the slots 38; this slottedconnection between the keepers 29 and 30 and the links 35 and 36permitting of the retraction of the keepers independent of the lockcylinder 37 on the insertion of the terminations of the hasp into thelock casing.

In the operation of the invention, the hasp 19 is normally disposed asindicated in dotted lines in Fig. 1, and full lines in Fig. 2 when notemployed to lock the cycle; the hasp 19 being retained in this positionby reason of the engagement of the spring clips 28 therewith. When it isdesired to lock the cycle the hasp 19 is elevated and rocked on thepivotal connections of the links 21 and 22 and is moved astride of thefork members 7 and 8 and one or more of the cycle wheel spokes 20.

The downturned terminations 17 and 18 are then introduced into theapertures 15 and 16 where they are engaged by the keepers 29 and 30 asparticularly shown in Fig. '5, thus locking the hasp 19 which. by reasonof its engagement with the spokes 20 of the cycle wheel will effectivelylock the cycle against use. To disengage the keeper 29 the lock cylinder37 is operated as before described by means of a key 40 as is common tothe cylinder locks, whereupon the hasp 19 may be rocked on its pivotalconnections and restored to its inoperative position.
